TYPICAL ASPHALT LOCATIONS: Refer final drawings.

1. Behind Start platform - front of staging area2. Front side of Start Hill ( option vs concrete ) 3. Berms (NB: best completed after settling period to ensure no subsidence )4. Asphalt Pumptrack (proposed)

STANDARDS: Materials used and work carried out shall be in accordance with AS 2734 Asphalt Paving - guide to good practice and shall comply with the requirements:

- AS 1141 Methods of sampling and Testing Aggregates.- AS 1160 Bitumen emulsion for construction and maintenance.- AS 2150 Hot mix asphalt

MATERIALS:Subgrade: Shall be compacted engineered fill (VENM OR ENM) . Base course: 100mm DGB20 to 98%MDDBitumen emulsion tack coat 2L/M.SQUAREWear course: 30-40mm Dense residential Grade AC10

CONSTRUCTION: Compact subgrade using an approved rammer or roller to a density of 98% modified A.A.S.H.L. to a minimum depth of 150mm.

Apply and compact base course using an approved rammer or roller to a density of 98% modified A.A.S.H.L. to a minimum depth of 100mm.

Place a 2-5mm tack coat of bitumen emulsion evenly over a thoroughly swept and prepared base. The emulsion shall be to AS 1160 and designation AMS/170-60 with care taken to ensure no overspray on to edgings and surrounding finishes.

Over a set tack coat layer install 30-40mm residential grade AC10mm layer. Aggregate to be up to 10mm crushed blue metal.

Finishing: Where possible a light hand roller should first be used to achieve desired shape and finishing. Following a lead compactor plate is to be utilised to achieve finish.

REINSTATEMENT: Reinstatement works shall include but not be limited to:- Cleaning off foreign matter such as oil, bitumen etc. - Replacement of elements where required.

Final track width

‘Snail trail’ width.. approx. 2m wider than final track width

Typical straight construction cross section

1. SNAIL TRAIL'Snail Trail'. Works should seek to first establish a 200mm minimum high snail trail of track tread path at the widths 2m wider than the final required width for each straight. This ensures proper drainage and minimising maintenance to the BMX track. Additionally the establishing of the 'snail trail' into the site should aim to maintain slight fall throughout the length of the track if possible. The snail trail should begin to follow the final RL’s for the overall track design. This point is not a point whereby riders can test the track shapes.

2. TRACK TREAD PATH Built over the top of the Snail trail the tread path should be about achieving the final compacted shapes safe and enjoyable. Builders should seek to achieve a smooth compacted surface such that test riders can test the length, height and shape of the features through the track.

3. SAND/POLYMER MEMBRANE SURFACE This type of surface is only high performing when on a perfectly finished non-subsiding base has already been established. The track should be perfectly groomed, compacted and rideable prior to any application of a polymer surface. The sand/polymer surface then seals this level of track making it more resilient to weather.Polymer surfaces can be integrated with sand, dolorite, crusher dust and decomposed granitic.

UCI Requirements

Length: Between 300m and 400m (Note: the UCI may accept tracks up to 450m in length, if the winner’s race time will still be in the range of 35 to 38 seconds).

Minimum Width:• Events on the UCI International BMX Calendar:

o Start Hill: 10mo First straight:8mo First corner: 8mo Other straights and corners:6m

• Tracks for other events: o Start Hill: 10m

o First straight:8mo First corner:6mo All other straights and corners: 5m

Best PracticeThe widths mentioned above refer to the width of the riding surface of the track as measured between the outside edges of the two boundary lines on opposite sides of the track. The track should be planned so that there is a small shoulder of up to 25cm width outside each boundary line to ensure that the full width of the track can be ridden safely.

Other Requirements• Minimum distance from the bottom of the start hill to the beginning of the first jump: 5m

o Often, more space than this is preferred to allow time for some pedalling.

• Minimum length of the first straight measured from the bottom of the start hill to the entrance of the first corner: 70m *Note:Tracks for other events can have a first straight that is less than 70m; however at least 70m is strongly recommended

• Minimum distance from the exit of the first corner to the lip of the take-off of the first jump on the second straight: 20m

• Minimum flat distance from the end of the last obstacle to the finish line: 10m

• Minimum stopping distance after the finish-line: 35m (can be a bit less, depending on traction given by the surface and grade; but it must be sufficient to allow riders to stop after crossing the finish line)
