There are a large number of high liquid limit soil distributed in southern China. As one of the special soils commonly seen in highway construction, high liquid limit soil cannot be used in subgrade filling directly due to its special engineering properties. With the idea of saving engineering investment and protecting environment, high liquid limit soil must be improved to be qualified subgrad...

The pavement constructions on soft and expansive soils are not durable and unable to sustain heavy traffic loading. As a result, pavement failures and settlement problems will occur very often even under light traffic loading due to cyclic and rolling effects. Geotechnical engineers have dwelled deeply into this matter, and adopt various methods to improve the engineering characteristics of sof...

The paper presents experimental results from unconfined compression and splitting tensile tests used in combination order to estimate the cohesion intercept of unsaturated soils. Samples different soils form slurry were subjected various suction values using axis translation technique a pressure plate extractor then these samples removed tests. Mohr’ circles for two loading conditions drawn tan...

The quality of the cement-treated soil columns is normally assured based on unconfined compressive strength qu core samples. samples varies spatially and statistical parameters are adopted in assurance procedures. evaluated from sample strengths have a uncertainty depending size. present study investigates influence size evaluation overall column. A probabilistic framework which Bayesian infere...

The feasibility of propagating road materials in the use of contracture wastes especially contented great amount waste bricks were researched in three aspects: Performance of recycled aggregate, mechanical properties of renewable road materials, compression splitting indexes. Conclusions are as following: recycled aggregates contenting great amount waste bricks in place of natural aggregates ar...

Soil reinforcement can be considered as the combination of two parts. One part is soil for compressive stress capacity and another part is some material such as geosynthetics such as steel belts and fibers for tensile stress capacity. Soil improvement is one of the useful methods to increase the strength parameters of the soil. The main goal of this study is to evaluate the effects of GFRP on t...

Biostabilization is a newly proposed method to improve the strength and durability of geomaterials, it can serve as an alternative chemical mechanical stabilization. The objectives this study are perform biostabilization treatments for selected roadway construction geomaterials evaluate effects on engineering properties geomaterials. Three types were selected, two them compacted soil from unpav...
