This British Standard specifies requirements for the transport, laying and compaction of those asphalt mixtures conforming to BS EN 13108-1, BS EN 13108-4 and BS EN 13108-5, described in PD 6691, 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 tack coats and bond coats. While this standard does not include explicit requirements for asphalt materials covered in other parts of BS EN 13108 or other proprietary asphalt mixtures, the general requirements of this standard may be applied to those mixtures, in addition to special requirements for particular mixtures as laid down in individual quality plans and/or method statements.
NOTE 1 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, coated macadam, hot
rolled asphalt, stone mastic asphalt (SMA), porous asphalt 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. Protocols for the initial type testing of asphalt materials in accordance with BS EN 13108-20 Type testing are included in Annex C, Annex D, Annex E, Annex F and Annex G.
NOTE 2 BS EN 13108-20 Type testing details the way in which the conformity of a mix composition to the requirements of the specification is to be determined. This is similar to a mix design validation or job mix trial. BS EN 13108-20 offers some choice in the way in which specimens are to be prepared for the purposes of initial type testing. Since the results determined will depend on the method of specimen preparation, a set of
protocols showing the recommended UK selection of such procedures, linked to the recommended specification levels and classes, is included in this standard.
In the case of hot rolled asphalt (HRA), requirements are specified for providing a rough-textured surface on the surface course for skid-resistance. This standard does not include requirements for asphalt incorporating bitumen emulsion binders.

This standard defines terms specific to, and in general use by, fire protection agencies.
Fire safety engineering and fire testing terms are covered in BS EN ISO 13943.
This standard does not include terms where the standard dictionary definition is applicable. Neither does
it include terms and definitions which are unique to any small specialized discipline within fire safety.

Life Cycle Assessment: Principles, Practice and Prospects
Author: Ralph Horne, Tim Grant, Karli Verghese | Size: 4 MB | Format:PDF | Publisher: CSIRO Publishing | Year: 2009 | pages: 175 | ISBN: 9780643094529
Life Cycle Assessment (LCA) has developed in Australia over the last 20 years into a technique for systematically identifying the resource flows and environmental impacts associated with the provision of products and services. Interest in LCA has accelerated alongside growing demand to assess and reduce greenhouse gas emissions across different manufacturing and service sectors.
Life Cycle Assessment focuses on the reflective practice of LCA, and provides critical insight into the technique and how it can be used as a problem-solving tool. It describes the distinctive strengths and limitations of LCA, with an emphasis on practice in Australia, as well as the application of LCA in waste management, the built environment, water and agriculture. Supported by examples and case studies, each chapter investigates contemporary challenges for environmental assessment and performance improvement in these key sectors.
LCA methodologies are compared to the emerging climate change mitigation policy and practice techniques, and the uptake of ‘quick’ LCA and management tools are considered in the light of current and changing environmental agendas. The authors also debate the future prospects for LCA technique and applications.
