Semi-Flexible Base's Material Properties and Pavement Structure Applicability

ICTE 2011, 2011
For the special nature of semi-flexible base's road performance, this paper studies the Marshall stability, splitting strength and compressive strength tests of the semi-flexible mixture. First, several steps which should be taken to achieve the optimal mix proportion are presented as below: optimal gradation, optimal fluid content, optimal asphalt ...

Utilization of Waste Rubber Powder in Semi-Flexible Pavement

Key Engineering Materials, 2014
The central concept of semi-flexible pavement (SFP) is to combine the best qualities of concrete and asphalt pavement by means of filling the voids of the large gap asphalt mixture (LGAM) with good fluidity grout. The major purpose of this study is to determine the feasibility of utilizing waste rubber powder in the grout so as to reduce the stiffness ...

Formulation and performance comparison of grouting materials for semi-flexible pavement

Construction and Building Materials, 2016
Abstract Semi-flexible pavement has been widely used for good performance, however, few studies have been made on effects of composition and formulation on grouting material. Therefore, this paper focuses on effects of composition and formulation on two typical grouting materials, including cement paste and cement mortar.

Influences of matrix asphalt on performance of irrigated semi-flexible pavement

AIP Conference Proceedings, 2019
In order to find out the suitable asphalt types and corresponding voidage of the Irrigated semi-flexible pavement(ISFP), SBS modified asphalt and 70# road petroleum asphalt were used to form the matrix asphalt mixture with voidage of 10%, 15%, 20%, 25%, 30%, 35%.
