Protection blocks for the construction of roads and strip roads
Access roads are a vital part of daily life in South Africa. These roads are used for residential, commercial traffic and applications such as agricultural and farm roads in plantations andforests. These roads are subject to a variety of traffic loads from cars to heavy trucks carrying produce and workers. The use of Armorflex®180 and 205 as strip roads is a cost effective solution to the problems associated with gravel roads and earth tracks. These can become impassable in wet weather, causing considerable inconvenience and cost implications for commercial activities. The high cost of maintaining gravel roads and earth tracks can also be reduced making Armorflex® strips roads an economically viable solution.
