Study on the Influence of the Fiber and Modified Asphalt upon the Performance…
The effect of fiber on the asphalt mixtures has been concerned at all times. Bearing this problem in mind, four kinds of polyester fiber, one kind of methyl cellulose, one kind of mineral fiber, AC-16 and SMA-16 asphalt mixtures, AH-70 and the SBS (I-D) modified asphalt were chosen and used in the present study. Practical performances such as Marshall Test indexes, low-temperature split strengt…
Determination of Subgrade Resilient Modulus for Existing Pavement Based on Mo…
Subgrade resilient modulus (ER) is a crucial parameter for pavement design and evaluation with a mechanistic-empirical method. To existing pavement overlaying and reconstruction, ER is difficult to determine because it is a function of both water content and stress level. In this paper, a 3-stage method to determine ER considering moisture condition coupled with stress is presented. Firstly, th…
Rutting Resistance of Asphalt Pavements with Fine Sand Subgrade under Full-Sc…
The rutting performance of an asphalt pavement structure with a fine sand subgrade and a high groundwater table was evaluated with full-scale trafficking tests with the Mobile Load Simulator 66 (MLS66) on Chong-ming Island, Shanghai.The purpose was to establish the reliability of the design with fine sand.There were two test sections with the same asphalt pavement structure but different subgra…
FRP-Strengthened Metallic Structures
epairing or strengthening failing metallic structures traditionally involves using bulky and heavy external steel plates that often pose their own problems. The plates are generally prone to corrosion and overall fatigue. Fiber-reinforced polymer (FRP), a composite material made of a polymer matrix reinforced with fibers, offers a great alternative for strengthening metallic structures, especia…
Research on Strength Charcteristic Parameter of Sandy Pebble Soil Based on Di…
Sandy pebble soil is widely distributed in our country. Lots of studies show that sandy pebble soil makes dynamic behavior not clear due to typical discreteness of gravels and random geometrical distribution. This paper quantitatively analyzes the law of the strength characteristics of sandy pebble tunnel surrounding rock under different density and moisture content conditions through large-s…
