Perhaps the main reason to apply a preventive maintenance treatment to an HMA pavement is to reduce the aging of the asphalt binder and therefore maintain a higher level of pavement performance.

Some research has documented the aging of asphalt through traffic loadings. However, the. Optimal Timing of pavement Preventive M aintenance. Treatments for preventive maintenance are a solution that is recognized but still in the acceptance phase; effective models covering.

A lack of adequate guidance on the timing of preventive maintenance treatments was the main motivation for this study. and Zimmerman, K. NCHRP Report Optimal Timing of Pavement Preventive Maintenance Treatment Applications.

Transportation Research Board of the National Optimizing the Cost-Effectiveness and Time of Application of. The main goal of this research was to help users determine the proper timing of preventive maintenance by identifying how environmental aging affects asphalt material properties (binder andor mixture) in the pavement and how the application of pavement preservation treatments impact the aging process.

Two main test sections. Preventive-maintenance treatments help preserve pavements and delay deterioration caused by traffic loads and environmental conditions.

However, guidance is needed to ensure cost effectiveness of treatments, the benefit-to-cost ratio of different treatments applied based on time. Preventive Maintenance and Pavement Preservation A preventive maintenance program is a systematic approach to using a series of preventive maintenance treatments over time.

One treatment will improve the quality of the pavement surface and extend the pavement life, but the true benefits of pavement maintenance are realized when there is a.

Optimal application of pavement preservation or preventive maintenance is critical for highway agencies to allocate the limited budget for different treatments.

This study developed an integrated life-cycle cost analysis (LCCA) model to quantify the impact of pavement preservation on agency cost and vehicle operation cost (VOC) and analyzed the optimal timing of preservation treatments Cited by: If the deterioration rate of old pavement is lower than mkmyear, the benefit is maximized when the roughness level is between and mkm.

Findings from this study can be used as a guide to help determine optimal pavement maintenance : Qiao Dong, Qiao Dong, Qiao Dong, Xueqin Chen, Xueqin Chen, Xueqin Chen, Xiang Ma, Xiang Ma, Xiang Ma.

One of the major tasks in any transportation agency pavement management system is to select the appropriate method for rehabilitation and maintenance. There is a need to understand how preventive maintenance improves the performance of the existing pavements, to develop new techniques, and to determine the optimal timing for the application of.

Crack sealing in asphalt concrete (AC) overlays is an important component of pavement preventive maintenance. The objectives of this study were to evaluate the cost-effectiveness of crack sealing applied on AC overlays (flexible and composite) in Louisiana considering the pre-treatment overlay conditions and to determine the optimal timing of crack sealing.

The work or functions of expressway maintenance quality evaluating, pavement performance predicting, optimum selecting of preventive maintenance treatment, the optimal timing determining, and post. Optimal PM schedules are useful for pavement management decision-support because they can provide an indication of what preventive treatment is needed and when it is needed, and can thus help in estimating highway pavement monetary needs in the period between resurfacing events, in an optimal manner.

Develop and use statewide preventive maintenance specifications for every treatment type to establish uniformity. Provide training addressing preventive maintenance and pavement management concepts, pavement and treatment selection, materials, application. An evaluation of two pavement preventive maintenance techniques, namely, chip seal and sand seal coating, is described.

The evaluation Seal coat treatment is a broad term embracing several types of focuses on the identification of the optimal timing of application of seal coats.

This was achieved by using life cycle cost analysis. Peshkin DG, Hoerner TE, Zimmerman, KA () Optimal timing of pavement preventive maintenance treatment applications, NCHRP, Rep. TRB, Washington, D.Labi S, Sinha KC () Life-Cycle Evaluation of Flexible Pavement Preventive Maintenance.

sometimes accompanied by an additional layer of gravel or crushed aggregate. When timed correctly, successive pres-ervation treatments can extend the time needed before.

1. Introduction. With the ever-increasing traffic volume and loads, and the formation of traffic channelization, different degrees and types of distresses occur in asphalt pavement, such as rutting, cracking, and degradation of roughness.

In view of the life-cycle cost-effectiveness, preventive maintenance was introduced to establish a maintenance optimization decision-making. The application of PM treatments is a critical part of the pavement preservation program.

The report also includes suggested guidelines on the application of preservation treatments on high-volume roadways. Optimal Timing of Pavement Preventive Maintenance.

Regarding the PSI improvements and effective lives of preventive maintenance activities, Labi and Sinha () used data on Indiana pavements to build seal coating effectiveness predictive models.

Peshkin et al. () suggested the timing cycles and effective periods for different preventive maintenance treatments. Abstract. The short-term cost-effectiveness of maintenance treatments in asphalt pavement were evaluated based on the pavement historical maintenance records and pavement performance data from the pavement management system (PMS) in Jiangsu province, China.

Pavement preventive maintenance narrows that focus to the application of one or more treatments, generally to the surface of a structurally sound roadway. (a to benefit with preventive maintenance treatments) are reporting the benefits of pavement preventive maintenance are considered important by nearly every agency responding.

The software should select the right preventive maintenance or rehabilitation treatment based on the condition of the road is critical to a successful pavement management system.

The treatment selection system must also be easy for Metro to understand and change. Prioritization: Prioritize a maintenance rehabilitation schedule. The life-cycle cost of the preventive maintenance techniques was obtained using a Monte Carlo simulation.

Among the principal results, it was found that chip seals are the most cost-effective treatment and present the lowest life-cycle cost variability. The effective life of all three treatments. Typically, preventive pavement maintenance treatments are applied while the pavement is in a relatively good condition.

Usually, on the scale of 0 towhere represents a new pavement, the first preventive maintenance treatment is applied before the pavement condition drops below Figure 1 also shows the effect of a preventive maintenance.

seal can be used as a preventive maintenance treatment on a flexible pavement in good condition or as a stop­ gap maintenance treatment on a flexible pavement in poor condition. In the case of diamond grinding, the performance of this treatment is highly dependent on the quality and type of aggregates in the existing pave­ ment.

Asphalt concrete has been widely used in road engineering as a surface material. Meanwhile, ultrasonic testing technology has also been developed rapidly. Aiming to evaluate the feasibility of the ultrasonic wave method, the present work reports a laboratory investigation on damage detection of asphalt concrete using piezo-ultrasonic wave technology.

The gradation of AC was selected and. Flexible Pavement Maintenance and Repair Techniques Maintenance and repair of flexible pavements can take a number of basic forms and still other variants on those basic themes. This brief introduction is intended as an overview of the techniques that are more typically used in the Delaware region.

One of the key steps in the highway investment decision-making process is to conduct project evaluation. The existing project level life-cycle cost analysis approaches for estimating project benefits maintain limited capacity of probabilistic risk assessments of input factors such as highway agency costs, traffic growth rates, and discount rates.
