and urban and suburban roads.
COLAS CZ operates 11 modern and powerful hot asphalt mixing plants for production of asphalt mixtures. Our dense network of production plants enables us to supply building sites throughout the Czech Republic.
- HAMP Rančířov in the district Jihlava,
- HAMP Bystřice nad Pernštejnem in the district nad Sázavou,
- HAMP Tasovice in the district Znojmo,
- HAMP Holubice in the district Vyškov,
- HAMP Sedlnice in the district Nový Jičín,
- HAMP Bašnice in the district Jičín,
- HAMP Soutice in the district Benešov,
- HAMP Sudoměřice u Bechyně in the district Tábor
- HAMP Čenkov in the district Praha-východ,
- HAMP Bradlec in the district Mladá Boleslav,
- HAMP Valdorf, Horšovský Týn in the district Domažlice.
Currently, COLAS CZ mixing plants produce about 700 thousand tons of asphalt mixtures per year.
Asphalt mixtures and modified asphalts
In addition to the traditional mixtures (ACO, ACL, ACP, BBTM, SMA, PA and AKO), we also offer mixtures based on the technological rules of the Ministry of Transport CR and mixtures developed in the laboratory of the COLAS SA group in France:
High modulus asphalt mixture is a hot-processed asphalt mixture with a high rigidity modulus, with a relatively high content of harder asphalts (or additional hardening additives), low voidage for base courses and modified voidage for the sub-base courses. The application of these mixtures minimizes the occurrence of excessive permanent deformation in the form of ruts or other similar defects, thus ensuring the high resistance of asphalt layers against wear and effects of water, long life, the reduced thickness of the road compared to the classic types of modifications and higher operational efficiency of the roadway.

Asphalt mixture with increased resistance to crack spreading (SAL) – a specially designed mixture for thin or micro asphalt topping. At low temperatures, the ductility of the layer is several times higher than that of standard mixtures or materials, thus reducing the spread of cracks during the movement of the lower layer. (source: TP 147)
MICROVILLE asphalt soundproofing mixture – an asphalt mixture with 0/8 mm granularity for wearing courses in areas where it is necessary to reduce noise produced by tyres of passing vehicles. The mixture is also very resistant to effects of the traffic load, has excellent anti-skid properties and resistance to permanent deformations (it is used as a thin-layer modification).
Asphalt colour mixture COLCLAIR – This mixture is analogous to the traditional asphalt mixtures, but the standard black asphalt is replaced with Bituclair transparent binders. The mixture can be produced simply with the aggregate and binders or fibres, and the appearance follows the natural hue of the aggregate, or with added pigments. (source)
We are able to produce other mixtures to satisfy the customer's needs.
