Asphalt in bags / Cold Mix Asphalt. Bitumer DIPLAX

Bitumer DIPLAX


Diplax is a special type of mineral and bituminous cold-applied mixture. It can be used in any weather conditions between -20 oC to +60 oC. It is an out-of-the-box solution. Does not require any specialized equipment. Any rehabilitation work is waste-free, and the excess of the mix can be reused in different repairs.

Repair works do not cause traffic disruptions as repairs are carried out quickly, and the surface is immediately ready to use. Repair works can be carried out in any weather conditions, also in sub-zero temperatures after prior removal of ice, as well as during downpour without the need of removing water.


Cold-applied, for express, durable repair work of asphalt and concrete surfaces. Filling in defects after installation works: gas, hydraulic, electrical, etc. Allows to eliminate defects of any shape, depth and size.


Includes removing damaged surface sections and cleaning the defect of loose parts and debris. This phase of work requires removing chipped fragments of the surface around the area of repair. Edges should be


Damaged and cracked asphalt in the area of repair should be chipped off manually or with a jack hammer.


The chipped asphalt fragments should be removed from the repaired area and the surface should then be dusted off, for example with compressed air.


Priming of the filled defect is not required. However, using a primer increases the efficiency of the repairs due to increased adhesiveness of DIPLAX.


Repairs are carried out by filling the cavity with repair material. After the defect has been filled with DIPLAX, the mix layer undergoes preliminarily, manual compaction. It is recommended that the minimal depth of the repaired cavity be no less that 30 mm, and the maximum thickness of a single layer should not exceed 60 mm post-compaction. In case of deeper defects, it is recommended to fill the layers up to 100 mm deep. DIPLAX mix can be applied in the temperatures between -20°C – +40°C, except for periods of intense rainfall and snow. In order to ensure proper workability, it is recommended to use a mix not cooler than +5°C.


The mix can be compacted manually or mechanically. For manual compaction, a metal rammer up to 20 kg is used. For mechanical compaction, a plate compactor or a steel roller is used. In case of manual compaction, the thickness of the layers should not exceed 30 mm. To top surface of the compacted mixture should be located from 1 to 3 mm above the existing surface. The drop of the repair layer should be consistent with the drop of the repaired surface.


While working in temperature exceeding 20°C, the outer layer of the mixture should be gritted with 0.2 or 0.4 mm granulated sand. Do not cover the repaired cavity with asphalt binder. Bonding (hardening) of the mixture occurs after evaporation of the volatile components. Renovated fragments of the surface can be used immediately after repairs.

How to Use Asphalt in a Bag for Pothole Repair

Once we’ve prepared everything, it’s time to get started. This step-by-step guide explains how to repair a pothole with asphalt patch from a bag.

Begin by filling the hole with cold mix asphalt and make sure you have enough of this material so that there is no dip or depression in its surface afterwards. If required, warm up the product or add kerosene for easier application before use.

Preparing the Area

To effectively and durably repair a pothole, it is paramount to properly prepare the area prior to doing so. This will involve cleaning the space and assessing its condition in order for optimal adhesion of the patch material. The required tools are an asphalt shovel, brushes & squeegees, sweepers with a wire street broom attachment, crack cleaner machine as well as heat lance equipment.

A handy tool which can be used when dealing with bag-applied asphalt patches is that of a pothole calculator. This assesses width/length measurements before accurately producing depth numbers needed for successful repairs.

Applying the Asphalt

Pothole repair requires the right weather conditions – ideally, temperatures of 20° Celsius or higher. A minimum thickness for each layer of asphalt in a bag should be 3 to 4 inches (25mm). In order to achieve this desired patch job, it is important that dirt and debris are removed from the hole prior to application. Then add cold mix asphalt up until its surface meets even with surrounding pavement levels before compacting it down firmly.

Finishing Touches

When the pothole repair with bagged asphalt is complete, it’s time for some finishing touches. The ideal tools to use are a wire street broom, shovel or lute/rake and tamper tool, together with an asphalt roller or plate as well as a specific pothole tamper. To produce smooth results while working on such repairs using pre-made asphalt mix packs, first make sure you clean up the area prior to application then compress everything in place by running over it all with your chosen device of choice i.e. either a rolling wheeler contraption or an average platting implement!
