Highway D400 Surface Boxes Our Highway D400 surface boxes come with indexed covers, enlarged frame corners and are 70+ PSRV tested. Meeting the needs of National Highways CD 534 v0.1.0 with HighwayNational Highways has updated CD 534, a significant set of its requirements for manhole covers and gully grates installed on their road network. First released in February 2020 and updated to version 0.1.0 as of May 2022. Frame flange areaCD 534 v0.1.0 now sets a minimum flange area of 190,000mm² for D400 and 285,000mm² for E600 covers, this equates to 2.1N/mm² as in HA 104/09. Frame depth and weightA 150mm frame depth is now required on motorways and all purpose trunk roads. A lower limit frame weight is also specified to ensure frames are stiff enough. Skid resistanceThe WRc test mehod is now the only accepted test method for calculating skid resistance on raised chequer. This test measures a small tyre’s resistance to sideways slip caused by the cover surface. D400 or E600E600 manhole covers are to be installed in place of D400 covers where the Annual Average Daily Traffic (AADT) of light goods vehicles travelled on a road is greater than 1,500 in each direction. Check road traffic statistics for AADT
> 1,500 Annual Average Daily Traffic (AADT)?With the introduction of CD 534 there were several key changes. This includes the requirement for E600 manhole covers to be installed in place of D400 covers where the Annual Average Daily Traffic (AADT) of light goods vehicles travelled on a road is greater than 1,500 in each direction. As a "rule of thumb", most A roads will have an annual average daily traffic number over 1,500 light goods vehicles. Full traffic data can be found for many locations around the UK on the Government website.
