Roadways fail because they wear out under the load of traffic and due to weather induced slow decay.
Deterioration will happen, gradually but surely – within five, ten or twenty years, depending on how a road was initially built. Adinotec’s technology can be deployed to put that moment off into an ever more distant future.
Adinotec’s technology goes to the heart of a road’s body: the base course. The black top is any roads pretty face. But what goes on inside the body determines its health. The fundamentals are:
- unconfined compressive strength
- stiffness as defined by the modulus of elasticity
- coefficient and rate of expansion
- flexural strength
- freeze-thaw durability
These five parameters determine the lifespan of roadways.
How Perenium® works
In combination with hydraulic binders, Perenium® thoroughly increases the filling in and sealing action in voids remaining in compacted base courses.
The result is:
- better penetration of capillary structures because of enhanced viscosity of the binder
- significant mitigation of water infiltration risks in base courses, thus increasing frost resistance
- reinforced compressive strength through non-polluting synthetic latex components
- heightened flexural strength, durability and fatigue resistance
- improvement of material properties of a variety of soil categories with different grain sizes
How it is made
- Improves the material properties of hydraulic binders
- Generates significant cost savings per square meter in new road construction and particularly in refurbishments
- Achieves top quality, increased load bearing capacity and durability with reduced base course thickness
- Significant improvement of frost resistance
- Fast workflow, up to 2x quicker compared to conventional road construction
- Most of the old base course material can be reused – removal and disposal is no longer required
- Measurably lessens the environmental impact caused by transport movements
- Less disruption of road traffic as a result of fewer truck movements at the construction site and shorter construction times
- In-situ processing renders sourcing of replacement base course material largely redundant
- Suitable for the improvement of almost all types of soil
- Mixed-in-Place construction method generates cost savings
- Less hydraulic binder material required
- Construction work can continue at low outside temperatures
- Lower deformability of the base course favours a decrease in asphalt layer thickness
Perenium is Adinotec’s flagship brand. It encompasses a range of products which all of them have a decisive effect on all five road-health indicators:
Perenium FL is a latex based Polymer in liquid form. It is combined with hydraulic binders used in base course stabilisation, but also in soil improvement measures under difficult conditions.
Perenium DX is a re-emulsifiable latex-based Polymer-powder. Precisely dosed with liquid it supplements hydraulic binders in stabilising difficult soils used in base courses.
All products are combined with a bespoke in-situ application method. Adinotec delivers a scientifically grounded technology package to assures optimum efficiency in construction:
- fast work progress
- limited road closures to traffic
- drastically reduced environmental footprint
In-situ-application means there is no need for excavating the old road aggregate and trucking it away to landfills or to recycling plants. Adinotec’s process re-mills all acceptable old asphalt and aggregates to obtain a homogenous grain-size range. The in-situ-reworked aggregate material is evenly blended with hydraulic binder material and Perenium in precisely measured quantities and during accurately timed working windows to yield optimum strength and water resistance. Toxic residues in the old roadbeds are neutralised. Also, since no new material has to be brought in, the project carbon footprint can be cut down below a tenth compared with traditional road construction methods.
Faster work progression, less truck runs, shorter closing times for traffic – they all result in cost savings and in an environmentally sustainable way of building roadways.
