Abstract

There is still a lack of suitable methods for evaluating pavement functional performance according to the characteristics of real-world environment and traffic. This study developed an acceleration test method based on the Driving Wheel Pavement Analyser (DWPA) to evaluate the anti-sliding properties, anti-stripping properties, and tire–pavement noise of AC-13, SMA-13, and OGFC-13 asphalt mixtures, and MS-1, MS-2, and MS-3 micro-surfacing materials. The results indicate that the OGFC-13 mixture exhibited the largest texture depth, and the SMA-13 mixture exhibited the largest British pendulum number (BPN) at the end of the test. The MS-3 material had the best anti-sliding performance among the micro-surfacing materials. Coarse gradation improved the anti-stripping performance of the micro-surfacing materials. The tire–pavement noise for all materials increased with the increase of wheel repetitions. The OGFC-13 mixture and MS-3 micro-surfacing material exhibited the best and worse noise reduction performance, respectively. The new measurement method for evaluating the pavement surface functional performance was proved to be efficient.

Highlights

Transportation is a fundamental and evolving national industry, which provides important support for economic and social development
The tire–pavement noise of SMA-13 was reduced in the low-frequency band compared to AC-13
OGFC-13, the texture depth of SMA-13 was better than thatand of AC-13 and MS-3

Summary

Introduction

Transportation is a fundamental and evolving national industry, which provides important support for economic and social development. By the end of 2018, China’s total highway mileage had exceeded 4.856 million km [1,2]. With the continuous growth of highway mileage and service time, the new concept of “equal emphasis on construction and maintenance” has gradually been accepted for highway development. Pavement maintenance has become a key task for the Department of Transportation in China. There have been many studies performed on pavement maintenance and preservation [3,4], new types of maintenance measures and materials are still needed to cope with new demands, such as rapid maintenance under heavy traffic conditions. Engineering research focused on the bearing capacity of pavement structures [5,6,7,8]
