Techniques long been in use…
In-situ stabilization techniques have long been used throughout the World for pavement construction and rehabilitation. Such techniques have historically been chosen predominantly because of their significant cost savings.
With the advent of green-road sustainability systems for roadway design and construction, there naturally exists a growth expectation for stabilization products, such as Durament, which focuses on both the benefits of pavement stabilization while taking into consideration the social and environmental benefits of using in-situ material.
The need for quality construction aggregates for buildings, roads, utilities, and transportation infrastructure construction and associated maintenance continues to grow across Canada, and around the world, placing ever-increasing demands on non-renewable aggregate resources (pits and quarries), fuels and binders (asphalt cements and Portland cements). At the same time, there is also increasing waste management environmental pressure to keep all potentially reusable and recyclable materials from taking up valuable space in ever-scarce landfills and pressure to reduce energy consumption and green house gas emissions.
Canadian municipalities spend $12 to $15 billion annually on infrastructure but it never seems to be enough. Existing infrastructure is aging while demand grows for more and better roads, responding to higher standards of safety, environmental protection as well as population growth.
In the past 25 years, there has been considerable interest in developing new construction materials incorporating in-situ materials.
