Maintenance Techniques

With the aggravation of high grade highway asphalt pavement destructions, it becomes particularly important to maintain pavement performance and enhance road economic efficiency. The asphalt pavement preventive maintenance technology is an effective technique to extend pavement services and maintain pavement performance. In this paper, we combine the decay model of pavement performance with assets value evaluation idea and establish an analytical method about preventive maintenance technology based on assets evaluation. An example of hot asphalt overlay is also presented, it is found that preventive maintenance techniques can reduce the attenuation of road infrastructure assets value and maintain pavement performance efficiently.

Lca Results

Preventive maintenance (PM) is regarded as the most economical maintenance strategy for asphalt pavement, but the life cycle environmental impacts (LCEI) of different PM techniques have not yet been comprehensively assessed and compared, thus hindering sustainable PM planning. This study aims to comprehensively estimate and compared the LCEI of five PM techniques then propose measures to reduce environmental impacts in PM design by using life cycle assessment (LCA), including fog seal with sand, micro-surfacing, composite seal, ultra-thin asphalt overlay, and thin asphalt overlay. Afterwards, ten kinds of LCEI categories and energy consumption of PM techniques were compared from the LCA phases, and inventory inputs perspectives, respectively. Results show that fog seal with sand and micro-surfacing can lower all LCEI scores by more than 50%. The environmental performance of five PM techniques provided by sensitivity analysis indicated that service life may not create significant impact on LCA results to some extent. Moreover, four PM combination plans were developed and compared for environmental performance, and results show that the PM plan only includes seal coat techniques that can reduce the total LCEI by 7–29% in pavement life. Increasing the frequency of seal coat techniques can make the PM plans more sustainable.

Application Analysis

In domestic asphalt pavement micro-surfacing technology is a new kind of pavement maintenance technology. Starting with the micro-surfacing technology application effect, we analyzed the micro-surfacing technology characteristics and application conditions. We also analyzed and discussed the application prospect, strive to provide a technical reference for promotion and application of micro surfacing technology.

In this paper, the abilities of recovery and regeneration for aged asphalt of a new type of asphalt pavement maintenance agent are studied. The agent is applied in the construction of test section of Yuhe Road, and the pavement performances before and after the construction are compared. The test indicates that after the maintenance agent is added into aged asphalt, the penetration and ductility are effectively improved, the softening point is lowered. When the penetration depth of agent reaches 6 mm，the texture depth , friction coefficient and antiskid value are improved to some extent ,the water permeability coefficient is reduced, and the appearance of pavement is improved as well，The paper provided reference for the applying curing agent of asphalt pavement to the preventive maintenance system.

The results of a study conducted to assess the relative performance of different flexible pavement rehabilitation treatments, including the influence of pretreatment condition and other factors, are presented. The data used in the study were drawn from the Long-Term Pavement Performance Studies' Specific Pavement Study (SPS) SPS-5 and General Pavement Study (GPS) GPS-6B experiments. The rehabilitation treatments used in the SPS-5 experiment are 2- and 5-in. overlays with virgin or recycled asphalt concrete mixes with or without preoverlay milling. Overlay thickness and preoverlay roughness levels were the two factors that most influenced the performance of the asphalt overlays of asphalt pavements in the SPS-5 experiment with respect to roughness, rutting, and fatigue cracking. Over the long term, the 5-in. overlays outperformed the 2-in. overlays with respect to roughness, rutting, and fatigue cracking. Overlay mix type (virgin versus recycled) and preoverlay preparation (with or without milling) had slight and inconsistent effects. The average initial postoverlay international roughness index of an asphalt overlay of an asphalt pavement was found to be 0.98 m/km. The data show a slight but statistically significant tendency for asphalt pavements overlaid when they were rougher to have more initial roughness after overlay than asphalt pavements overlaid when they were smoother. The data show that, on average, about 6 mm of rutting develops in the first year or so after placement of an asphalt overlay of an asphalt pavement. This is presumably due to compaction of the mix by traffic and appears to be independent of the overlay thickness, mix type, preoverlay preparation, and preoverlay rutting level.

Topsis Model

As a fundamental work for pavement maintenance management, the evaluation on asphalt pavement performance is the premise of determining the maintenance time and strategy. Aiming at the shortcomings of traditional TOPSIS model, an improved TOPSIS method is proposed to make comprehensive assessment on asphalt pavement performance. Instead of the Euclid distance, the vertical distance between the evaluation object and positive ideal solution is taken as the basis for alternatives ranking. A case study is carried out, indicating that this approach is rational and feasible. The result can provide a certain reference for the road management department to make optimal decision.
