PROJECT OVERVIEW
PROJECT CHALLENGES
The project was very challenging due to the loading required from 300mm Layer. The Haul Road is to be used to cart excavated material with some 50No 45tn Dump trucks trafficking every day.
A combination of Lime and Cement was used to acheive the required loadings. A period of mellowing was required to allow the Lime to breakdown the Clays. The mellowing period and follow on cement works had to be co-ordinated to ensure all works were trimmed and compacted before the end of each shift.
Management of Logistics and deliveries of Binder are challenging on HS2 with prebooking and certifified delivery trucks etc only allowed on site.
