Roadbase Suppliers for Construction, Trade and Public also welcome

        • Road Base Gold Coast
        • Road base CBR 15 2.5,  CBR 45 2.3, and CBR 60 2.1 Roadbase available. Gold Coast Gravel Supplies Roadbase Manufactured for maximum Compaction, ideal for Driveways, Site access roads, Hardstands, Site sheds and rural access and Road and pavement construction.A blend of aggregates and fines that compacts to make a stable hard base. It is most resistant to water erosion. Generally roadbase is used in areas of heavy traffic like road construction and haul roads.

Manufacturing

The production from a manufacturing quarry, involves taking a range of various aggregate sizes, made available during the crushing process, and recombining them into a balanced formula that produces the required properties specific to a given application. The finished product must meet the specified requirements of grading, workability, placeability, strength, density, long-term durability and appearance. For this reason, the supplier needs to clearly understand the properties of the aggregate constituents intended to be used in the roadbase, so repeatable and reproducible measurable engineering properties can be achieved in the final product.

Water and Compaction

The quantity of water within a specific roadbase blend is critical to enable the particles to come together, during placement and compaction, in a manner that allows as much air as possible to be removed and only aggregate particles left to fill the voids within the rock skeleton. This will ensure that even distribution of all the particles throughout the mix, has occurred even after compaction has taken place. Too little water within the roadbase during placement and compaction can have the effect of allowing particles to segregate or be broken down and thus in situations density will not be able to be obtained. Too much water and the overwork required to dry back can further breakdown aggregate particles and lead to segregation affecting the ability to obtain proper compaction within that roadbase layer. Improper compaction can lead to a multitude of issues and ultimately pavement failure in a shorter time than allowed for in the design. One of the main issues arising from undercompaction of road base layers will be rutting of the surface.
This will be due to the movement of particle during cycles of wetting and drying during the life of the pavement.
