Asphalt is also made to fail Its main failure mode is cracking with a potential that increases over time due to the age hardening of the asphalt binder — a natural aging process of the material According to the Asphalt Institute "Pavement distresses accumulate as asphalt pavements age and traffic pounds them

road material stabilisation is taking place in Zimbabwe resulting in serious cost increases As chemical stabilisation is being increasingly used to improve the quality of sub-standard road pavement materials and to recycle old pavement materials in Zimbabwe the number of problems seems to be increasing correspondingly

on the soil-cement to complete the pavement Soil-cement is sometimes called cement-stabilized base or cement-treated aggregate base Regardless of the name the principles governing its composition and construction are the same 1 2 Cement Stabilisation The hydrated products of cement bind the soil particles the strength developed depending

Leading Supplier of G1 G2 G3 G4 G5 G6 and G7 road base and subbase materials in South Africa Deuces Group is a premium supplier of road base and subbase materials to the civil and construction industry in South Africa Specifically designed to provide supporting structures in any pavement design our road base and subbase material

A cement-modified soil (CMS) is a soil material that has been treated with a relatively small proportion of portland cement – less cement than is required to produce hardened soil-cement The objective of the treatment is to amend undesirable properties of problem soils or substandard materials so that they are suitable for use in construction

GEOWEB Benefits for Roadbase Stabilization Creates a stable base layer that reduces vertical pressures and lateral stresses on subgrade soils Creates a stiffened base layer and the resulting increase in base strength can be used to reduce the pavement depth design up to 30%

Sudspave is a permeable paving grid system of interlocking cellular plastic porous pavers designed for the stabilisation of trafficked grass or gravel surfaces Used where a free-draining permeable gravel or grass car park access road or driveway is required
