Technical Guide for the Pavement Preventive Maintenance
The evaluation of asphalt pavement technical condition is expressed by Pavement Quality Index (PQI) and Pavement Condition Index (PCI), Road Quality Index (RQI), Rutting Depth Index (RDI), Skid Resistance Index (SRI) and Pavement Structural Strength Index (PSSI). The range of PQI and corresponding sub-index is 1–100.Reclaimed asphalt pavement (RAP) was tested as aggregate replacement for concrete.

Asphalt pavement classification using smartphone accelerometer and
A comprehensive experimental evaluation was performed on three datasets that represent different scenarios of asphalt pavement classification. The proposed approach reaches a classification accuracy of 80% to 98% in the three evaluated problems and we experimentally show that the complexity invariance substantially improves the results However, to determine the asphalt pavement gradation segregation in humid and hot environments, a multi-indicator analysis method was used in this study to achieve an accurate evaluation of the asphalt pavement gradation segregation by air void content. The pavement gradation separation was evaluated based on the air void content Uniformity evaluation of asphalt pavements in hot and

(PDF) Pavement Performance Evaluation of Asphalt
Based on this, a pavement quality evaluation based on machine learning, SVM, and other techniques is established, and a comprehensive evaluation model based on SVM, a set of asphalt pavementAged asphalt pavement was milled, rubblized and reused in new pavement construction, which was known as reclaimed asphalt pavement (RAP) material (Zhao et al., 2020). Although additional RAP decreased the cost and increased the high temperature stability of the pavement, it was found that asphalt pavement with RAP tended to perform Evaluation of pavement performance for reclaimed asphalt materials

Study on the interlayer bonding state of an asphalt pavement
The interlayer bonding of an asphalt pavement significantly influences the mechanical properties and long-term durability of the pavement structure. In order to develop a rapid and comprehensive evaluation method for assessing the interlayer condition of asphalt pavements using 3D GPR, we propose the stacking peak ratio (SPR) method. Additionally, reasonable texture evaluation algorithm should be optimized. 5. Conclusions. The state-of-the-art publications related to texture of asphalt pavement have been reviewed in terms of characteristics, measurement methods and relationship with skid resistance performance. The following conclusions can be obtained. (1)A state-of-the-art review of asphalt pavement surface
