27 | G | It emerges from the factory rolled, like a carpet, onto a drum 1.5 metres in diameter. On site, it is unrolled and stuck onto its foundation with bitumen. | Paragraph G;
Lines 1 – 2 |
28 | D | Hot asphalt, mixed with small stones, is spread into the mould by a rail mounted machine which flattens the asphalt mix with a roller. When it sets, the 10-millimetre-thick sheet has a surface smoother than anything that can be achieved by conventional methods. | Paragraph D;
Lines 4 – end |
29 | J | The success of Kuijpers’ design will depend on how much it eventually costs. | Paragraph J;
Line 3 |
30 | B | Houses become harder to sell where environmental noise is high, and people are not as efficient or productive at work. | Paragraph B;
Last line |
31 | I | On large highways, trucks tend to use the inside lane, so resonators here could be tuned to absorb sounds at around 600 hertz while those in other lanes could deal with higher frequency noise from cars. | Paragraph I;
Last line |
32 | C | He set out to tackle the three most important factors: surface texture, hardness and ability to absorb sound. | Paragraph C;
Last line |
