This British Standard specifies requirements for the transport, laying and compaction of asphalt mixtures conforming to BSEN13108‑1, BSEN13108‑4and BSEN13108‑5, and described in PD6691, from the time that they leave the mixing plant until they are placed on the road ready to receive a superimposed layer or traffic. It also includes requirements for preliminary work at the laying site needed to ensure that the substrate is fit to receive the asphalt and for the application of bond coats.

Although this standard does not contain explicit requirements for asphalt materials covered in other parts of BSEN13108or other proprietary asphalt mixtures, the general requirements of this standard can be applied to those mixtures, in addition to special requirements for particular mixtures specified in individual quality plans and/or method statements.

NOTE1 The term “asphalt” used in this standard is the generic term used to describe the wide range of mixtures of aggregate and bituminous binder individually known as asphalt concrete (AC), hot rolled asphalt (HRA), stone mastic asphalt (SMA), porous asphalt (PA) or mastic asphalt and other proprietary materials which are available for use in constructing and maintaining roads and other paved areas that are on the market in the UK.

NOTE2 Methods for ensuring that the correct surface drainage characteristics are imparted to pavements with PA surface course are outside the scope of this British Standard.

NOTE3 BSEN13108‑20 specifies tests for determining the conformity of a mix to any of the other parts of BSEN13108. This is similar to a mix design validation or job mix trial. BSEN13108‑20offers some choice in the way in which specimens are to be prepared for the purposes of product‑type testing. Requirements for sample preparation for the demonstration of product‑type test properties are given in PD6691:2015, Clause13and are linked to the relevant protocols/annexes in this British Standard, as relevant.

In the case of HRA, a mixture design protocol is provided as informative text in AnnexH, and requirements are specified for providing a rough‑textured surface on the surface course to provide skid‑resistance.

This standard does not specify requirements for asphalt incorporating bitumen emulsion binders.

This standard does not cover additional or specific requirements relating to the laying and compaction of reduced temperature asphalts.

NOTE4 BSEN13108is being reviewed and it is anticipated that any revisions might cover low‑temperature and cold mixtures.
