The major objective of this research was to discuss the effects of loading rate on the flexural-tension properties and uniaxial compressive strength of micro-surfacing mixture using three-point bending test and uniaxial compressive test respectively.As a preventive maintenance surface treatment on asphalt pavement,micro-surfacing was formed the basis for the ISSA recommendation of an optimum micro-surfacing design.Tests were conducted over a wide range of temperature to investigate the difference of properties from low loading rate to a relatively high loading rate.Three-point bending test was used to study the flexural strength,strain and modulus of micro-surfacing mixture,and uniaxial compressive test was carried out to obtain the relationship between strength and the loading rate as well as temperature.Experimental results showed that flexural strength at high loading rate was larger than that at low loading rate.The flexural strength difference between low and high loading rate enlarged when the temperature rose.The flexural strain at high loading rate increased compared with results of the low loading rate.Regressive parameters from exponent-law equation of the flexural modulus were compared between the two loading rates,and it shown that micro-surfacing mixture exhibited better anti-cracking characteristic at low temperature when given a relatively low loading rate.Results of uniaxial compressive test revealed that the strength difference of micro-surfacing among different loading rates decreased with the increase of temperature. The logarithm relationship between the strength and loading rate over a wide range of temperature was obtained to compare the experimental and predicted values which resulting in a reasonable consistency.
