PS/25/28 Road Coring and Materials Testing Framework Agreement

Description

Ayrshire Roads Alliance (East Ayrshire Council and South Ayrshire Council) is required to deliver a programme of works, including carriageway surfacing, footway surfacing and structural maintenance. Material testing prior to and during the works is required to identify issues during the design stage and ensure the quality of the finished product. Lot 1: Lot 1 - Coring and Testing to determine Coal Tar Content (Two Stage) This Lot will cover the sampling and testing of bituminous road pavement materials (generally by extracted road pavement core) to determine if coal tar is present within the layers of the road pavement. The procedure will include for an initial test (generally using the PAK marker paint method) to determine the presence of coal tar and, if coal tar is indicated, laboratory analysis to determine and confirm if coal tar is present and, if so, the amount of coal tar present (Stage 2). Lot 2: Lot 2 - Lot 2a - Sampling and Testing of Construction Materials and Lot 2b - Sampling and Testing of Bituminous Materials This Lot will primarily encompass the sampling, testing and analysis of a variety of road construction materials including, but not limited to, the following: Unbound stone/aggregate materials; Cementitious materials bituminous pavement materials including surface dressing; bituminous pavement characteristics (e.g. skid resistance, texture depth, surface regularity and strength) Lot 3: Lot 3 – Testing of Thermoplastic Road Markings This Lot is for the testing of thermoplastic road markings for Retroflection, Colour, Skid Resistance and Reflection. Lot 4: Lot 4 – Testing of Soil & Ground Conditions This Lot will encompass a range of site investigation services that will include, but not be limited to: Trial pits to determine ground conditions, material layers, and for material sampling in both superficial deposits/soils and in bituminous pavements. Extraction of soil samples using hand auger techniques. Ground Penetrating Radar survey to identify changes in ground conditions and voids.
