Firstly, there is no tack coat or mixing required prior to application of EZ Street Asphalt - EZ Street is ready to use.
EZ Street Asphalt works in water and all weather conditions.
As EZ Street is a cold product and curing is not based on temperature, any cold joints / paver joints merge together to form one clean smooth mat from curb to curb. Cold Joints are recognized as an inbuilt weak point in any pavement surface. Except for any sub base / subsurface failures, the cold joint will inevitably be the first area of the pavement where failures will occur. The elimination of the cold joints through the use of EZ Street will reduce future road maintenance costs as well as potentially extending the usable life of the pavement itself.
The EZ Street mat / surface will always remain slightly flexible through the life of the pavement. The product itself will remain slightly active through its life which will enable it to move fractionally with the movement of the traffic and the road structure itself. This movement does not lead to rutting or permanent deformation in the material but does result in the pavement being able to resist some reflective cracking and will also self-heal for any cracks that do appear.
Just as EZ Street Asphalt can be stored on site prior to the paving operation, there will be no wasted material when paving with it. With regular hot asphalt, any material not used through the paver is traditionally dumped as it gets cold and turns hard. As EZ Street Asphalt is not a temperature based material and will not go off, cure or turn hard like regular asphalt, any unused EZ Street product can be returned to the stockpile for reuse at a later date giving a 100% material usage. There are no longer concerns with under or over ordering of product or the potential for product loss due to on site delays or machinery breakdown.
Any paving project will use 10% less EZ Street Asphalt per tonne than regular asphalt. For instance a paving job using 1,000 mt of asphalt will use only 900mt of EZ Street. EZ Street Asphalt is approximately 10% lighter per tonne than regular asphalt. The specific weight of the product is around 2.2 tonnes/m3 versus asphalt at around 2.4 tonnes/m3. This allows for approximately 10% extra square meters paved per tonne than can be completed with regular asphalt.
Paving with EZ Street Cold Asphalt dramatically reduces traffic noise produced by regular pavement and asphalt. The polymer within the EZ Street mix and the open grading of the cold asphalt combined absorb a significant amount of tire and road noise producing measurable sound reduction in the pavement. This is an ideal product for noise sensitive areas such as roads around hospitals and schools, etc. EZ Street Asphalt can also be used to pave quiet roads within residential neighborhoods generating significant cost savings by reducing the amount of sound barrier fencing on new or existing highways and project sites.
EZ Street is a polymer modified cold asphalt that can be used in virtually any weather condition. The benefit that this brings to a paving operation is that planning and programming can be made well in advance with no considerations having to be made for inclement weather on the day of installation. Rain snow or shine, the paving can still take place. EZ Street Asphalt can be utilized in sub-zero temperatures thus another benefit is the ability to extend the paving season further into the winter throughout the province. The shelf life of EZ Street enables the product to be stockpiled and stored on site in advance of the paving operation taking place. Product will not have to be picked up from the asphalt plant and taken to the project site on the day of paving. This in itself can be a significant saving as it can reduce the number of trucks required to deliver from the asphalt plant to the on-site stockpile. In the event that there is no space on site for storage, EZ Street can be taken directly from the depot stockpile (in urban areas) and delivered to the site eliminating any reliance on an asphalt plant co-ordination and one less activity to manage when performing a paving operation.
The product is always made in advance of the installation. Whether this is a week in advance or four months in advance, there is never a situation where the asphalt production and the paving are required to work in conjunction. The logistical relief this provides is extremely beneficial for any paving project.
Paving with EZ Street Asphalt is an easier operation than paving with regular asphalt. Firstly, the paving equipment is cold as it is paving a cold product - plenty of time is available between the paving and the rolling to hand level and rake. This operation can even wait until the paving is completely finished before starting to rake, a process that can only lead to problems when working with hot asphalt. Secondly, the crew numbers required for the paving operation can be reduced as there is no longer the need for large crews to work in the time constraints required when paving with hot asphalt.
EZ Street Asphalt can be used in any geographical location totally independent of the location of an asphalt plant. Regular asphalt is limited in the distance it can realistically be transported from the plant due to the “window” the temperature of the product allows.
