With modern economic and social development, the technical and economic requirements of highway maintenance and construction projects have become increasingly complicated. Meticulous and in-depth investigation and demonstration guided by scientific theories and methods are of considerable importance to highway maintenance scheme decision. As basis for the selection of highway asphalt pavement recycling maintenance scheme, the factors influencing the decision are analytically demonstrated and an evaluation system is proposed, including three major decision indexes: applicability of recycling mode, recycled pavement quality recovery index, and economic benefit. According to the principles of data statistics and analysis, this study proposes a calculation method for the recycled pavement quality recovery index, analyzes the economic benefits of decision schemes using economic models such as recycling ratio and cost, and puts forward an optimal evaluation method of engineering cost and its fuzzy score intervals. Index weights are calculated through the analytic hierarchy process, and the comprehensive decision evaluation system and comprehensive evaluation method are established. Subsequently, the decision-making method is analyzed on the basis of the decision system by combining the related data. Results show maximum weight of the pavement quality recovery index and minor differences among four recycling schemes in the quality recovery index and applicability. The decision-making results are simplified with clear hierarchical feature because of the fuzzy score intervals of each index. Findings can provide a reference for the asphalt pavement recycling scheme decision.

Planning Methodology

In recent years, various highway agencies and researchers have worked to develop efficient methods for maintenance planning, without much success. A major reason is that they usually neglect user inconvenience and delay costs, which alone can greatly exceed the maintenance costs. It is known that different maintenance plans have very different effects on users and on highway performance. These interactions have not been intensively explored, and the existing analysis methods are not quite satisfactory. To remedy the existing deficiencies, the development of a realistic and efficient maintenance planning methodology is proposed. Specifically, the proposed approach incorporates several components already developed for selecting and scheduling interdependent projects in transportation networks; however, it organizes them in a more efficient way. The proposed maintenance planning methodology can overcome the main weaknesses of prevailing methods and help decision makers to greatly reduce user costs and improve the efficiency of highway maintenance operations.

Hierarchy Process

With the rapid development of China's transportation and the improvement of people's living standards, China's highways have entered the peak maintenance period. According to the old road conditions and financial conditions, how to choose the appropriate maintenance technology to meet the technical and economic requirements of highway maintenance and construction projects has become a difficult problem faced by highway maintenance management departments. Therefore, based on the principle of index selection, this study comprehensively considered the impact of various factors on maintenance decision-making, determined four evaluation indexes, and systematically studied the compre-hensive decision-making system of asphalt pavement recycling maintenance. Based on the subjective-objective linkage and probability statistics method, the eigenvalue of the applicability of recycling mode was transformed to the same scale of 0 to 100, and the fuzzy scoring interval of the four bids was proposed. The calculation method of pavement quality recovery index (PQRI) and the analysis basis of economic benefits were clarified. Finally, the weight of each index was calculated by analytic hierarchy process, and the multi-index comprehensive decision-making method of pavement maintenance is constructed and used to theoretically verify and guide the actual road section. Results demonstrate that the proposed PQRI can realize the operability of quantifying the later operation of pavement. The weight of each index from big to small is PQRI > economic benefit > applicability of recycling mode. The recycled pavement quality recovery indices and applicability of the four recycling modes have small differences, and the proposed four bids interval makes the decision-making evaluation process more simple and explicit. The decision evaluation results of actual road section verify the rationality and practicability of the decision method. The conclusions are important for the maintenance and management of asphalt pavement recycling technology.

The incorporation of reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS) in asphalt mixes is encouraged as long as the modified mix exhibits equal or improved performance. Through the integration and data mining from several statewide databases, and extensive laboratory and field testing, this paper investigates the performance of asphalt mixes containing RAP, RAS, or both relative to similar mixes with virgin components. The integration of several databases permitted a network-level investigation of performance patterns. The reasonableness of the observed performance patterns was assessed using the results from the Hamburg wheel tracking tests (HWTT) and indirect tensile strength tests performed on specimens from several sites included in a network-level database. Furthermore, the retrieved network-level data were cross-referenced to the results from a historical performance database. At project level, HWTT and the overlay tester tests were performed on samples from several dozen sites to characterize laboratory performance. Field performance of these sites was also documented through periodic cracking and rutting surveys. From the network-level assessment, the impact of RAP, RAS, or both on the performance of the mixes was found to be mix-dependent. The combination of RAP and RAS seems to negatively affect cracking resistance. Further, dense-graded and Superpave mixes with RAP, RAS, or both exhibit higher cracking potential with minimal impact on rutting resistance. The project-level field performance evaluation shows that fatigue cracking propagates at a higher rate for sections with RAP and RAS than for sections with only RAP.
