TL;DR: In this paper, experimental research conducted on the use of the chemical soil stabilizer Con-Aid for stabilization of low-cost roads and rehabilitation of existing roads was conducted in Botswana.
Abstract: During road construction, especially on unsurfaced earth and gravel roads, many problems can arise including deterioration of the surface and dust on the road. Because road maintenance is costly and disruptive to traffic flow, stabilization of some local road materials during construction is necessary. This paper discusses experimental research conducted on the use of the chemical soil stabilizer Con-Aid for stabilization of low cost roads and rehabilitation of existing roads. Con-Aid is a water-soluble, anionic compound with surface-active properties, and is non-toxic and environmentally friendly. Two types of soils in Botswana were used in the research, and lab tests on treated and untreated soil samples were carried out to establish the engineering properties of the soil. It is recommended that Con-Aid be used as a stabilizer on low cost roads, as it will reduce construction and maintenance costs, ensure that the roads remain passable in rainy season, and dust-free in dry season.

TL;DR: In this article, the authors present the current British practice in the design and specification of SOIL-CEMENTs for use in the base or base base for ROADS and the methods used to control the quality of the materials in practice.
Abstract: CURRENT BRITISH PRACTICE IN THE DESIGN AND SPECIFICATION OF SOIL-CEMENT FOR USE IN THE BASE OR SUBBASE FOR ROADS IS DESCRIBED. THE COMPOSITION OF THE MATERIAL, THE STRUCTURAL DESIGN OF ROADS INCORPORATING SOIL-CEMENT, AND THE METHODS USED TO CONTROL THE QUALITY OF THE MATERIAL IN PRACTICE ARE PRESENTED. THE SUITABILITY OF A SOIL FOR STABILIZATION IS BASED ON REQUIREMENTS SIMILAR TO THOSE IN THE UNITED STATES, GOOD GRADING, LOW PLASTICITY OF THE FINES, AND FREEDOM FROM DELETERIOUS CHEMICAL CONSTITUENTS. THE PEDOLOGICAL CLASSIFI- CATION OF A SOIL PROFILE IS USED TO ESTIMATE THE DEPTH OF SOIL UNSUITABLE FOR STABILIZATION, BECAUSE OF ORGANIC CONTENT. MEASUREMENTS OF THE PH OF A SOIL-CEMENT PASTE 1 HOUR AFTER MIXING ARE USED AS A CHECK ON THE PRESENCE OF DELETERIOUS ORGANIC MATTER. SOIL-CEMENT HAS BEEN WIDELY USED SINCE 1945 FOR THE CONSTRUCTION OF HOUSING ESTATE ROADS AND LOW-TRAFFIC RURAL ROADS. CEMENT-STABILIZED MATERIALS HAVE ALSO BEEN USED FOR THE CONSTRUCTION OF MAIN ROADS, IN PARTICULAR AS THE SUBBASE OF CONCRETE AND BITUMINOUS- SURFACED ROADS. THE QUALITY CONTROL OF SOIL-CEMENT DURING CONSTRUCTION IS BASED LARGELY ON TESTS TO CHECK THE STRENGTH AND STATE OF COMPACTION OF THE LAID MATERIAL.

TL;DR: The use of lignin-based biofuel co-products (BCPs) to stabilize pavement subgrade soil is an innovative idea and satisfies the needs of sustainable development in construction as discussed by the authors.
Abstract: Freezing-thawing cycles in soils reduce considerably the foundation capacity of buildings and infrastructure. In recent years, development of nontraditional stabilizers has created hundreds of new products for soil stabilization. Fiber portions of biomass (such as lignin) can be considered as byproducts of the conversion process, and these byproducts are generally used to produce octane booster fuels, bio-based products, and other chemical products. The use of lignin-based biofuel co-products (BCPs) to stabilize pavement subgrade soil is an innovative idea and satisfies the needs of sustainable development in construction. A series of laboratory tests, including unconsolidated undrained direct shear test, freeze-thaw durability test, and scanning electron microscope tests, was conducted to evaluate the effect of BCP addition on shear strength performance for four different soils encountered in Iowa. The results of this study indicate that BCPs are beneficial in the soil stabilization of low-quality materials for use in road construction.

TL;DR: In this article, the effects of fly ash on the soil plasticity, moisture density relationship, unconfined compressive strength, shear strength parameters, CBR (California Bearing Ratio) values, deformation parameters, and swell potential, were evaluated.
Abstract: Results of laboratory research focusing on soil stabilization, using fly ash without activators, are presented in the paper. Two types of fine-grained soils were tested: low to medium plasticity clay and very expansive, medium to high plasticity clay. Soil-fly ash mixtures were prepared at optimum fly ash contents (15 and 20 %). The effects of fly ash on the soil plasticity, moisture-density relationship, unconfined compressive strength, shear strength parameters, CBR (California Bearing Ratio) values, deformation parameters, and swell potential, were evaluated. Results obtained show that the use uf fly ash can significantly contribute to the improvement of soil properties.
